General Information Operating Your Furnace
Your model MGE unit is unique is that it is entirely self-contained in one compact cabinet. It uses outside air for gas combustion
and the products of combustion are exhausted by a power vent directly to the outside through the upper right corner of the exterior grille. If your unit is located at ground level or the exterior is on a balcony, you will able to observe the flue products
discharge area. On cold mornings during the heating cycle you may notice a vapor emitting from the discharge area. This is
normal.
Depending on your local or state building codes, you will have a power disconnect either adjacent to your unit or located at your
main electrical panel. Over-current protection will be provided at this point. Have your builder, dealer, or maintenance people show you how to turn the power on and off for your Magic-Pak
unit.
A field-supplied gas cock (valve) is located in the gas line entering the front of your unit. Manually turn the handle so it is in a parallel position to the gas line. This is the "OPEN" position.
Lighting Instructions
1. STOP! Read the previous safety information.
2. Turn off electrical power to the appliance.
3. Turn the thermostat to lowest setting.
4. Turn the gas valve knob to "ON" position (see Figure 1).
5. Turn on electrical power to the appliance.
6. Set the room thermostat to the desired temperature. If the thermostat "set" temperature is above room temperature
after the pre-purge time expires, main burner will light.
Gas Valve
Your unit is equipped with an energy saving, automatic, intermittent ignition control. The burners are automatically ignited at the beginning of each heating cycle and shut off when each cycle is completed. Your unit does not have a pilot requiring manual lighting.
For your safety - Read before operating
A WARNING
Before operating, smell around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle to the lowest point. Refer to "What to do if you smell gas" on page 1 if the odor of gas is present.
Use only your hand to turn the gas control knob; never use tools. If the knob will not turn by hand, don't try to repair it. Call a qualified service technician. Force or attempted repair may result in a fire or explosion.

Temperature Control
There are many types and styles of thermostats. Yours may look
different from the one pictured in Figure 2. However, almost all thermostats perform the same basic functions described in the following section.

Thermostat Operation Owner/User Maintenance
There are two switches located on the thermostat. One switch controls the heating and cooling functions. The other switch is
for "FAN" operation, either continuous or automatic. On the thermostat is the temperature range for the heating temperature
and the cooling temperature desired.
To put the system into operation, push the switch to either "HEAT" or "COOl" position. After you have chosen the type of
operation you desire, move the thermostat dial or lever to select the temperature you would like the system to maintain.
Fan Operation
You may wish to increase your comfort by setting your system for continuous air circulation of the indoor air. The fan switch on
the thermostat permits you to do this.
With the switch in the "ON" position, the fan will operate continuously. "AUTO" position gives fan operation only when
the unit is in either heating or cooling.
Maintenance Of Your Unit
There are routine maintenance steps you should take to keep your unit operating efficiently. This will assure longer life, lower
operating costs, and fewer service calls. Certain service and maintenance procedures require the skill of a trained service person who utilizes special tools and training. Personal injury can result if unqualified personnel attempt those procedures.
Your unit should be inspected and serviced at least once per year by a qualified service technician.
Periodic Inspections
Should your living area be part of an apartment or condominium complex, you are likely to have maintenance personnel who will provide all normal maintenance functions to keep your unit
operating at maximum efficiency. If you are responsible for this
maintenance, there are several key steps you will need to
perform. Your Magic-Pak unit will, in most cases, be located
behind a moveable opening or closet.
1,
Filter Remove the access panel on the top of the cabinet.
A screwdriver is needed to remove this panel. The filter is
immediately behind this panel and can easily be slid out of
the side channels which keep it in place in front of the
indoor blower. The filter may be vacuumed or preferably
washed, then dried and replaced. This is a washable filter that will last many years when properly cared for. When
inserting the filter in the side channels, make sure it does not touch the fins of the coil. Your filter should be checked
every 4 to 6 weeks.
2,
Indoor Coil This coil must be clean at all times, especially for efficient cooling performance. Should any lint or dirt collect on the coil fins, you can usually remove this
accumulation using an ordinary vacuum cleaner hose with
a crevice tool or brush attachment. Be careful, the coil fins
are very fragile and are easily damaged.
3,
Condensate Drain During cooling, the moisture removed from indoors collects on the indoor coil, drops to the drain
pan at the bottom of the coil and then drains away through
a plastic hose connected to the stub at the front of the drain
pan. The condensate then drains to the unit base pan.
Make sure this drain connection is kept open to keep
condensate from overflowing the pan.
4,
Outdoor Condensing Coil Ifyour unit is located at ground
level where outdoor debris can collect on the outdoor coil, you will need to periodically inspect and clean this coil
during the cooling season. Use of a vacuum or hose is
recommended. A dirty coil will cause inefficient operation
on cooling and it may also contribute to cooling service
problems. Be careful, the coil fins are very fragile and are
easily damaged.
Your Magic-Pak is designed to give many years of efficient, satisfactory service. However, the varied air pollutants com- monly found in most areas can affect longevity and safety. Chemicals contained in everyday household items such as laundry detergents, cleaning sprays, hair sprays, deodorizers,
and other products which produce airborne residuals may have an adverse affect upon the metals used to construct your appliance.
It is important that you periodically inspect your unit. Visually inspect all flue product carrying areas of the furnace, the vent-
air intake system, main gas burners, and heat exchanger. You will be able to make this observation by removing the access panel located on the center portion of the cabinet. A screw- driver is needed to remove this panel. A flashlight will be useful.
Make one inspection prior to the beginning of the heating season and another half way through the heating season.
Should you observe unusual amounts of rust, flakes, or other deposits, coatings, or corrosion, it is important that you call your authorized dealer at once to obtain a qualified
service inspection.

5,
Blower and Fan Motors These are direct drive, sealed
bearing motors and do not require lubrication or owner
maintenance. Access to these motors can be made only when the entire cooling chassis is removed by your
authorized service person or dealer.
Since the entire cooling section of your unit is a factory-sealed
system, only your authorized service dealer should be called to
make any necessary repairs or adjustments.
A.R.I. Capacity Certified
The Air-conditioning & Refrigeration Institute label assures you
of cooling capacity as shown on the rating plate.
